An electric motor that is fixed to a revolving frame, an electrical equipment that is supported by the revolving frame by using a vibration absorption mount, and a cable for establishing a connection between the electric motor and the electrical equipment are provided. A connector mounting member having an outer shape smaller than that of a box is provided in the box of the electrical equipment, and an equipment-side connector is provided in the connector mounting member. A cable-side connector of the cable is connected to the equipment-side connector, and a cable end portion of the cable is fixed to the box by a clamp member. As a result, the vibration that is transmitted to the cable can be matched with the vibration that is transmitted to the cable-side connector.
